Safety and efficacy of photobiomodulation in the treatment of pain
Photobiomodulation (PBM) is gaining recognition for its effectiveness in treating various types of pain, both acute and chronic. However, as with any therapeutic approach, it is essential to assess its safety standards and limitations to ensure optimal use. This page explores in depth the scientific evidence supporting the effectiveness of PBM, as well as the precautions and contraindications to consider.
Effectiveness validated by clinical studies
Numerous clinical studies have demonstrated the effectiveness of PBM in relieving pain. This technology is based on the use of specific wavelengths of light, which penetrate tissues to stimulate mitochondria and promote the production of cellular energy (ATP). This action reduces inflammation, improves local blood flow and modulates nerve signals responsible for pain.
For example, a study of patients with knee osteoarthritis found that those treated with PBM reported a significant decrease in pain and improved mobility. Similarly, research on neuropathic pain shows that PBM can reduce nerve hypersensitivity and restore sensory function.
Safety standards and usage protocols
PBM safety relies on strict protocols regarding light intensity, session duration, and treatment areas. PBM devices use low-intensity light emissions, which distinguishes them from surgical or abrasive lasers. These emissions do not cause excessive heat or tissue damage, ensuring safe use for a wide variety of patients.
However, it is crucial that sessions are supervised by trained professionals, who adjust settings according to individual needs. Common contraindications include areas directly exposed to metal implants that are not compatible with light, or regions with active infections.
Precautions and contraindications to take into account
Although PBM is generally considered safe, some precautions should be followed. Pregnant women should avoid treatments on the abdomen or lumbar region unless advised by a doctor. In addition, patients with active cancers or malignant tumors should not receive PBM on the affected areas, due to a lack of sufficient data on the effect of light on tumor cells.
Another important aspect is the correct use of the devices. Devices intended for home use should be approved by regulatory bodies and accompanied by clear guidelines to avoid inappropriate use.
Photobiomodulation and treatment personalization
One of the strengths of photobiomodulation lies in its flexibility of use, allowing protocols to be personalized according to individual needs. Each patient has a different sensitivity and biological response, which requires adaptation of parameters, such as session duration, light intensity, and treatment frequency. This tailor-made approach maximizes effectiveness while minimizing potential risks.
For example, an athlete suffering from muscle pain after intense exercise will not have the same needs as a geriatric patient treated for chronic joint pain. By adjusting the parameters to the therapeutic objectives, practitioners can offer optimized and adapted treatment.
Towards a wider integration in medical care
With the accumulation of scientific evidence and the improvement of technologies, photobiomodulation is increasingly adopted in medical centers and specialized clinics. By promoting a personalized and non-invasive approach, it meets the needs of a wide range of patients.
By combining PBM treatments with other therapeutic approaches, practitioners can offer comprehensive and effective care. This allows to treat not only the pain, but also its underlying causes, offering patients a sustainable solution adapted to their individual needs.
